Sludge is generally a product of sewage treatment, and is an extremely complex heterogeneous body composed of organic residues, bacterial cells, inorganic particles, colloids and the like. The main characteristics of the sludge are high water content (up to 99% or more), high organic content, easy to rot and odor, and finer particles, smaller specific gravity, and a gelatinous liquid state. The sludge treated in the environmental protection project generally refers to the sedimentation material generated during the treatment of the sewage by the sewage treatment plant and the floating foam floating on the surface of the sewage. Its complex composition contains a large number of microorganisms, pathogens, heavy metals and organic pollutants. Because it contains a large amount of harmful substances, it will become secondary pollution of sewage treatment plants if not properly disposed.
